[PATCH v4 0/7] vhost-vdpa multiqueue fixes

Posted by Si-Wei Liu 2 years ago

Hi,

This patch series attempt to fix a few issues in vhost-vdpa multiqueue functionality.

Patch #1 and #2 are the formal submission for RFC patch as in:
https://lore.kernel.org/qemu-devel/c3e931ee-1a1b-9c2f-2f59-cb4395c230f9@oracle.com/

Patch #3 through #6 are obviously small bug fixes. Please find the description of
each in the commit log.

Patch #7 is a workaround fix for the QEMU segfault described in:
https://lore.kernel.org/qemu-devel/4f2acb7a-d436-9d97-80b1-3308c1b396b5@oracle.com/


Thanks,
-Siwei

v4:
  - split off the vhost_vdpa_set_backend_cap patch

v3:
  - switch to LOG_GUEST_ERROR for guest trigger-able error
  - add temporary band-aid fix for QEMU crash due to recursive call

v2:
  - split off vhost_dev notifier patch from "align ctrl_vq index for non-mq
    guest for vhost_vdpa"
  - change assert to error message
  - rename vhost_vdpa_one_time_request to vhost_vdpa_first_dev for clarity
